Influence of Jahn-Teller ions on spin-lattice relaxation in ferrimagnets

摘要

Spin-lattice relaxation in fetrites can be enhanced by 3d{sup}n ions with t{sub}(2g) orbital Jahn-Teller effect capabilities. When exchange-ordered, Mn{sup}(3+), Fe{sup}(2+), Co{sup}(2+), Cu{sup}(2+) can stabilize orbital doublets from the t{sub}(2g) shell by spin-orbit interactions. This occurrence can also account for observed magnetoelastic effects.
